Thanks, Fizzy. Io is where many Groups are moving. There is a big back-up in transferring Group files from Yahoo to Io, but they are working hard to get it accomplished. It may take a few days for the Groups to have all of their files on their new website, but one should be able to access the Group even before all files are transferred. Feline Hyper-T has successfully transitioned, but still awaiting to be able to access some files with test results, etc.
Again, Feline Hyper-T is now at
